Provided is an LED lamp, comprising: a lampholder structure having a lamp socket (101) therein, a lamp cup (300) having a mounting hole (301), and an illuminant structure screw-connected into the mounting hole (301) and also screw-connected to the lamp socket (101) so as to be energized. The lampholder structure comprises an insulating lampholder (102) provided with the lamp socket (101) therein, and a connection base (103). The illuminant structure comprises: a lamp cap screw (201) capable of being screw-connected into the lamp socket (101) so as to be energized, an insulating hollow column (202) connected to the lamp cap screw (201), a driving device (203), a heatsink (204), a ceramic isolation structure (205) arranged on the heatsink (204) and made of a ceramic material, and an LED light source structure mounted and fixed on an upper end surface of the ceramic isolation structure (205). The ceramic isolation structure (205) is arranged between the heatsink (204) and the LED light source structure, so as to provide heat conduction and dissipation, and insulation. An internal thread (302) is arranged on an inner sidewall of the mounting hole (301) of the lamp cup (300), and an external thread (208) corresponding to and matching the internal thread (302) is arranged on an outer sidewall of the heatsink (204). The heatsink (204) can be screw-connected and fixed into the mounting hole (301) via engagement between the internal thread (302) and the external thread (208). In addition, the lamp cap screw (201) is simultaneously screw-connected and fixed into the lamp socket (101) to perform electrical connection. The present invention, in the above manner, provides an LED lamp having a novel and reasonable structure, high heat dissipating efficiency, good safety performance, simple and flexible installation and disassembly, and enabling convenient and rapid follow-on works of inspection, maintenance and replacement. |
